ICE SKATE Filed eb. 15, 1944 Patented Aug. 8, 1944 ICE SKATE WilliamSim, Ralston, and Katherine Mary Shields, Prestwick, ScotlandApplication February 15, 1944, Serial No. 522,424 In Great BritainJanuary 8, 1944 1 Claim.

This invention relates to improvements in ice skates used for exhibitionskating.

An ice skate according to the invention has a blade or runner formedwith a depending spike at its forward extremity, and, at a shortdistance behind the spike, with an inwardly directed tooth having aplane under face presenting in conjunction with the vertical face of thetooth near to the spike an edge transverse to the length of the blade.

In the accompanying drawing which illustrates the invention Fig. 1 is aperspective view of the improved skate as fitted to a boot for the leftfoot.

Fig. 2 is a fragmentary side elevation and Fig. 3 a fragmentary invertedplan view, of the front portion of the skate.

Fig. 4 is a horizontal section on the line 4--4 of Fig. 1.

As shown, the blade I of the skate is formed at the forward extremitywith a vertically depending spike 2 associated with which is a lug 3adapted to prevent excessive penetration of the spike 2 into the ice.

Close behind the spike 2 the blade is formed with a tooth 4 directedinwardly, that is, towards the right. The tooth 4 has a plane under face6 intersected by the vertical face of the tooth nearer to the spike 2 toform a sharp edge transverse to the length of the blade.

At its free end the tooth is chamfered, so that, if it enters a hole inthe ice, it will clear itself.

The outer end of the tooth 4 is chamfered dihedrally so as to form atthe outer end of the face 6 a sharp corner I, the outer end of the tooththus somewhat resembling the bow end of a ship.

The skate is particularly adapted for the performance of spinning on theice.

At the commencement of the spin, the performer moves in a circle aroundthe forward portion of the blade. As her heel rises, the skate travelsin a gradually diminishing circle, the sole of the tooth and the groundedges of the forward portion of the blade contacting with the ice. Asthe performer rises on her toes, the spike 2 digs into the ice and theperformer spins around a centre constituted by the spike, the sole 6 ofthe tooth 4 becoming free of the ice except for the edge 5.

In this position of minimum radius of spin the ice is not excessivelyground into powder and thrown upwards and outwards.

As will be understood, the skate for the right boot is to the oppositehand to that for the left boot.

We claim:

An ice skate having a blade formed with a depending spike at its forwardextremity, and, at a short distance behind the spike, with an inwardlydirected tooth having a plane under face presenting in conjunction withthe vertical face of the tooth near to the spike an edge transverse tothe length of the blade.
